[Acute cerebellitis in children: regarding different etiologies].

UNLABELLED Acute cerebellitis is usually infectious, post-infectious or post-vaccination. Rarer causes include toxic ones. The clinical presentation is usually benign, however, severe cases with brainstem compression may present as coma. Regarding three pediatric clinical cases, the authors make a brief review on this entity, with particular emphasis on its causes and imaging findings. CASE REPORTS Three cases of pediatric acute cerebellitis are presented- post-viral, after acute intoxication with carbon monoxide and after accidental ingestion of methadone. DISCUSSION The etiopathogenic mechanisms underlying the imaging changes found in each of the three cases presented are discussed. CONCLUSION An imaging examination confirms the diagnosis of cerebellitis and is important to monitor severe cases. MR is more sensitive than CT in the evaluation of the cerebellar parenchyma.
